Deep Check API

Used Car DeepCheck is an AI-ready pre-purchase used car valuation, vehicle pricing, and deal analysis API for buyers and agents. Use it before buying a used car to check if the asking price is fair, compare live dealer listings, estimate market value, fair value, negotiation target, and maximum buy price, then return BUY, NEGOTIATE, or WALK AWAY. Supports Canada and U.S. markets with optional VIN, mileage, trim, location, listing history, and market-turnover intelligence.
